The monodispersed Co_2O_3 UFP(ultrafine particles) sol was prepared by microemulsion method. The conditions of preparation such as oxidant, acidity and concentration of DBS (dodecylbenzene sulfonie acid sodium salt) were studied. The size distribution was about 3～7 nm, which was measured by smallangle X-ray scattering. Some optical and interfacial properties were studied.
